Carolina Essentials

  • Termite Pheromones This investigation demonstrates how soldier termites sense pheromones. Students observe and document motions of termites under 2 different conditions: pencil circles and pen circles. View »
  • Comparative Metamorphosis In this investigation, students observe development of 3 different insects from the larva or nymph stage through the adult stage. They also complete a comparative development study of metamorphosis, observing complete and incomplete metamorphosis. View »
  • Wisconsin Fast Plants® Monohybrid Crosses Inquiry In this scientific inquiry activity, students germinate F2 generation Wisconsin Fast Plants® seeds and identify the phenotypes and possible genotypes of the F2 generation plants. View »
  • Introduction to Wisconsin Fast Plants® Phenotypes In this inquiry activity, students investigate phenotypes using Wisconsin Fast Plants® seeds. After the seeds germinate, students identify the phenotypes and the possible associated genotype. View »
  • Which Leaf Shape Can Hold the Most Butterfly Eggs? In this elementary-level activity, students investigate the relationship between leaf shape and the number of butterfly eggs that can be laid on a leaf (grades K–5). View »
  • Using Algae Beads as a Model for Photosynthesis Introduce students to photosynthesis with fresh water algae. By creating algae beads (made of algae and sodium alginate solution), they indirectly observe the change in concentration of oxygen in beads that are exposed to different amounts of light. View »
  • Photosynthesis Introduce students to photosynthesis in a visual way. As Elodea uses carbon dioxide from an initial solution, a change in pH occurs, causing a color change in the solution. View »
  • Invertebrate Biodiversity and Abiotic Factors Understanding the relationships between biotic diversity and abiotic factors in an ecosystem can be a difficult task. Using soil invertebrates, students can identify both the number of species present in a soil sample and the number of individuals within a species. View »
  • Pill Bug Behavior Choices This introductory investigation into animal behavior uses pill bugs and choice chambers. Students begin with an experiment to test how pill bugs respond to humidity and can go on to design an inquiry to test another environmental factor. View »
  • The Ups and Downs of Weather Use this demonstration to show how temperature, pressure, and the Coriolis effect drive weather. View »
  • Thermochemistry: An Endothermic Reaction In this thermochemistry demonstration, students observe an extreme, spontaneous endothermic reaction between 2 solid compounds, measure changes in temperature, and make observations. View »
  • Equilibrium and Milk of Magnesia Rainbow This demonstration shows a colorful reaction that is a good introduction to Le Châtelier’s principle, solubility, stoichiometry, neutralization reactions, and reaction rates. View »
  • Carbon Snake In this teacher-directed demonstration of an exothermic reaction, students observe the dehydration of a carbohydrate using concentrated sulfuric acid. View »
